Nitrate Levels in the Rock Creek Park Watershed, Washington DC, 2: Variability part of Examples
Spreadsheets Across the Curriculum module/Geology of National Parks course. Students calculate standard deviation and z-values to examine a possible outlier in a positively skewed data set.

What Does the Mean Mean? Describing Eruptions at Riverside Geyser, Yellowstone National Park part of Examples
Spreadsheets Across the Curriculum/Geology of National Parks module. Students study measures of central tendency in a bimodal dataset of eruption intervals.

Porosity and Permeability of Magmas part of Examples
SSAC Physical Volcanology module. Students build a spreadsheet for an iterative calculation to find volume of bubbles and hence porosity, permeability and gas escape as a function of depth.

How Do We Estimate Magma Viscosity? part of Examples
SSAC Physical Volcanology module. Students build a spreadsheet to examine how magma viscosity varies with temperature, fraction of crystals, and water content using the non-Arrhenian VFT model.

Carbon Sequestration in Campus Trees part of Examples
Spreadsheets Across the Curriculum module. Students use allometric relationships to calculate tree mass from trunk diameter in a stand of trees in the Pacific Northwest.

Comparing Stream Discharge in Two Watersheds in Glacier National Park part of Examples
Spreadsheets Across the Curriculum module/Geology of National Parks course. Students study how discharge per unit area varies with elevation in the high country of Glacier National Park from USGS hydrograph data from Swiftcurrent Creek and its tributary Grinnell Creek..

A Percentage Stroll through Norris Geyser Basin, Yellowstone National Park part of Examples
Spreadsheets Across the Curriculum module/Geology of National Parks course. Students calculate percentages and percent differences to compare various measures of fumaroles, mud pots, hot springs and geysers in this introduction to hydrothermal features at Yellowstone NP.

Yellowstone! A National Park on a Hot Spot part of Examples
Spreadsheets Across the Curriculum module/Geology of National Parks course. Students use foundational math to study the velocity of the North American Plate over the hot spot, the volume of eruptive materials from it, and the recurrence interval of the cataclysmic eruptions.

From Isotopes to Temperature: Working With A Temperature Equation part of Examples
Spreadsheets Across the Curriculum module. Students build a spreadsheet to examine from a dataset the relation between oxygen isotopes in corals and the temperature of surrounding seawater.

Mined-Over Matter: Remembering Copper Mining at Keweenaw National Historic Park, Upper Peninsula Michigan part of Examples
Spreadsheets Across the Curriculum/Geology of National Parks module. Students calculate the amount of rock removed and the value of copper produced at the great Keweenaw District up to 1925.
